Create: Unlock Schematics

This mod is very simple and has a very specific use: it allows modpack makers to hide schematics from the Schematic Table.

Locked schematics should be placed in locked folder inside the schematics folder. The path would look like this: <instance>/schematics/locked/<schematic name>.nbt.

Then, to unlock the schematic you would use the command this mod adds:

/schematic unlock <schematic name>[.nbt]

• Schematic name can be with .nbt extensions or without.
• If schematic with same name already exists in the schematics folder, it will not be replaced. Player will receive a message that schematic is already unlocked.
• Due to the reason above - your locked schematics should have somewhat unique name, to avoid conflicts with user-created schematics.
• Command requires elevated permission level: cheats enabled, op, server owner, etc...

Knowledgeable folks may have already guessed how this works. Yes, it just copies the file from one folder to another.

Example: 

Unlocks the schematic on quest completion: 

Create is not required as a dependency. But, obviously, mod is pointless without it. 

Feel free to suggest a feature, if you need it for your modpack.
